Understanding Bitwise Operations
What are Bitwise Operations?
Bitwise operations are low-level operations that work directly on the individual bits of integer values. Unlike arithmetic operations that treat numbers as whole values, bitwise operations process each bit position independently. Our bitwise calculator supports all standard bitwise operators: AND, OR, XOR, NOT, NAND, NOR, XNOR, left shift, right shift, and unsigned right shift - the same operators available in C, C++, Java, JavaScript, Python, and virtually every programming language.
Bitwise operations are fundamental to systems programming, cryptography, network programming, graphics, and algorithm optimization. They are typically the fastest operations a CPU can perform, making them essential for performance-critical code.
How Our Bitwise Calculator Works
- Enter Your Values: Type one or two integers into the input fields. Our bitwise calculator accepts decimal (42), hexadecimal (0xFF), binary (0b1010), and octal (0o17) notation - mix and match as needed.
- Instant Browser-Based Processing:Select your operation and bit width, then click Calculate. All bitwise operations run entirely in your browser using JavaScript's native bitwise operators. No data is sent to any server.
- View Multi-Format Results: The bitwise calculator displays your result in decimal, binary, hexadecimal, and octal simultaneously. The bit visualizer shows each bit position as a colored cell so you can see exactly how the operation transforms your values.
Supported Bitwise Operations
- AND (a & b): Sets each bit to 1 only if both corresponding bits are 1. Used for masking - isolating specific bits by ANDing with a mask value.
- OR (a | b): Sets each bit to 1 if either corresponding bit is 1. Used for setting specific bits - turning bits on without affecting others.
- XOR (a ^ b): Sets each bit to 1 if the corresponding bits differ. Used for toggling bits, simple encryption, and detecting differences between values.
- NOT (~a): Inverts every bit - 0 becomes 1 and 1 becomes 0. The result is the bitwise complement, equivalent to -(a+1) for signed integers.
Shift Operations and Bit Width
Left shift (a << b) moves all bits b positions to the left, filling with zeros on the right - equivalent to multiplying by 2^b. Right shift (a >> b) moves bits right, preserving the sign bit for signed integers. Unsigned right shift (a >>> b) always fills with zeros regardless of sign. Our bitwise calculator supports 8-bit, 16-bit, and 32-bit widths so you can match the exact behavior of your target platform or data type.

Frequently Asked Questions About Bitwise Calculator
A bitwise calculator is a tool that performs bitwise operations - AND, OR, XOR, NOT, NAND, NOR, XNOR, and shift operations - on integer values and displays results in binary, decimal, hexadecimal, and octal. Our bitwise calculator runs entirely in your browser with no signup required.
AND sets a bit to 1 only when both input bits are 1 - used for masking. OR sets a bit to 1 when either input bit is 1 - used for setting bits. XOR sets a bit to 1 when the input bits differ - used for toggling bits and detecting changes. Our bitwise calculator shows the result of all three operations side by side.
NOT (~a) inverts every bit in the value - every 0 becomes 1 and every 1 becomes 0. For a signed 32-bit integer, NOT(a) equals -(a+1). For example, NOT(0) = -1 and NOT(255) = -256. Our bitwise calculator applies the NOT operation within your selected bit width.
Right shift (>>) is an arithmetic shift that preserves the sign bit - negative numbers stay negative. Unsigned right shift (>>>) always fills the leftmost bits with zeros regardless of the sign, treating the value as unsigned. For positive numbers, both produce the same result. Our bitwise calculator supports both variants.
Absolutely. All bitwise calculations run entirely in your browser using JavaScript's native bitwise operators. No data is sent to any server, and your numbers never leave your device. You can use our bitwise calculator online with complete privacy.
Yes - our bitwise calculator is 100% free with no signup, no account, no premium tier, and no usage limits. Perform as many bitwise operations as you need, at no cost.
Our bitwise calculator accepts decimal integers (e.g. 42), hexadecimal with 0x prefix (e.g. 0xFF), binary with 0b prefix (e.g. 0b1010), and octal with 0o prefix (e.g. 0o17). You can mix formats - for example, AND a decimal value with a hex mask.
Our bitwise calculator supports 8-bit, 16-bit, and 32-bit integer widths. The bit width determines how many bits are shown in the visualizer and how the result is masked. Choose 8-bit for byte operations, 16-bit for word operations, and 32-bit for standard integer operations.
To calculate a network address, enter the IP address as a decimal or hex value in Input A, enter the subnet mask in Input B, and select AND. For example, IP 192.168.1.100 (0xC0A80164) AND subnet mask 255.255.255.0 (0xFFFFFF00) gives the network address 192.168.1.0 (0xC0A80100).
